A very rare heathland species in Belgium, mainly observed in the Kempen and in the southern part of the country.
The larva lives in spun leaves in a silken tube on the lower parts on the food plant. The adults are readily disturbed during the day from out of vegetation. They become active during late afternoon and evening and later come to light.
The adults fly in one generation a year: from mid June till August.
The larva lives on Vaccinium uliginosum, V. oxycoccus and Calluna vulgaris.
